Joplin vs. Gravity Dropper vs. SBI Command Post vs. ?
I rode a bike yesterday with a Joplin remote-trigger adjustable seatpost -- first time using one of these. I'm sold. I need one.
I found old threads discussing these seatposts, but couldn't find a comparison or pros/cons of one vs. another. A guy I ride with says that the Joplin/Maverick ones tend to sag down while riding, and much prefers the Gravity Dropper (apparently all mechanical).
Anyone have a strong preference for any of these? FWIW, I need it for a 31.6mm seatpost. I think some of these adjustable posts only come in 27.2 and then use shims to fit larger sizes.
